Product Description

　　The YF35 series two-stage impulse steam turbine features a flow path incorporating two double-row velocity-compounding stages, with a maximum power output of 3,600 kW. This design retains the reliability of single-stage turbines while significantly improving internal efficiency by more than 8–20%. It is particularly suitable for applications where higher efficiency is not required, yet the pressure drop is relatively large—situations in which using a single-stage turbine would result in lower efficiency. Compared to a single-stage turbine at the same power output, the YF35 series exhibits a lower steam consumption rate; or, at the same steam flow rate, it delivers greater power output. The energy-saving benefits of the YF35 series are even more pronounced. The YF35 series two-stage steam turbine can also be configured as either a condensing-driven turbine or a power-generation turbine. Its key advantages include lower cost and excellent reliability.
